PATENT OFFICE PENNSYLVANIA, ASSIGNORS T() STEEL HEDDLE MAJVUFACTURINGCOMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIAI-IEDDLE FRAME' Application filed May 9, 1938- Seral No.v 276,215.

. Our invention relates to heddle frames for looms, and it relates moreparticularly to improved means for strengthening and stiffening the topand bottom rails of the frame intermediate the ends thereof.

The principal object of our present invention is to provide an improvedform of stay or brace extending between the top and bottom rails of theframe which will effectually prevent springing of the frame, thereby1nsuring freedom and easy play of the heddles on the heddle bars.

A further object of our invention is to provide an improved form of stayor brace which can be readily and conveniently mounted in and detachedfrom the frame, whereby certain of the heddles may, when required, beeasily shiftedV from one side to the other of the stay rod, to the endthat the same may at all times 'be properly arranged in the frame.

The nature and characteristic features of our invention will be morereadily understood from the following description, taken l, inconnection with the accompanying drawings forming part hereof, in which:

Figure 1 is a front elevation of a. heddle frame provided with a stay orbrace embodying the main features of our present invention Fig. 2 is an'enlarged fragmentary detail view, partly in elevation and partly insection, illustrating the manner of connecting the stay rod to the topand bottom rails of the frame; Y

Fig. 3 is a transverse section thereof, taken approximately on the line8 3 of Fig. 2, certain portions being shown in elevation Fig. 4 is aperspective view of a plate member provided with a spring tongue, thesame constituting a portion of the device forl looking the stay rod inthe operative position; and f Fig. 5 is a perspective view of one end ofv .mounted in each `spring tongue 17, which may be formed by hook endsby means of e from end to end ofthe heddle frame, and arranged near thetop and bottom rails thereof in the usual manner, are the heddle bars 8,upon which the heddles 9 are mounted and supported.

The stay rod proper comprises a thin, fiat .strip of metal 10, one ormore of these being provided, and suitably located in the heddle frameat desired places intermediate the ends thereof. Each end of the stayrod 10 isprovided with an aperture 11, which vis adapted to be extendingportion 12 of a hooi; member 13 ofthe rails 6, preferably by meansof ascrewthreaded portionvlt.

VMounted onthe inneredge of each ofthe rails 6, and secured thereto,preferably by means of screws 15, is a plate member 16. The plate member16 is providedwith a,

striking the same out from the body portion of the plate member `16. Theplate member f16 is apertured bevond the end of the tongue portion 17,andthrough this aperture the hook member i13 extends. It will be notedthat the free end ofthe springtongue extends under the horizontalextension 12-of the hook member 13.

The arrangement is such .that whenthe member 13 and the plate vmember16v are mounted in the rail 6, the Vendvof the tongue portion 17 of theplate member 16 will bear against the under side of thehorizontalextension 12 of the hook member 13, and will serve to retain the end ofthe stay rod 10` in its operative engagement. with the hook member 13. y

The stay rod 10 may also beprovided with suitably located recesses 19for the reception of the heddle bars 8, each recess 19 having anenlarged opening 20 for theengagement and disengagement of the heddlebar.

rIhe hook membersl and the plate members 16 are iixedly secured withrespect to the rails 6 in the manner hereinbefore described, and are notordinarilyl removed therefrom after once being positioned thereon. A Itis, however, well'known that where intermediate stay or bracel membersare used LOUIS KASIER, OF PIIILADELPHI,

nd straps 7. vExtending Y engaged by the horizontally the top and bottomrails,

in heddle frames, it is frequently necessary to shift some of theheddles upon the heddle bars from one side to the other of the stay rod,in order to secure an even arrangement of the warp ends in the weave,and for this reason it is desirable that the stay rods be more or lesseasily removable and replaceable whenA desired.

lVhen the stay rod is being mounted in the frame, the aperture 11 at oneend of the rod is brought into engagement with one of the hook members,the spring tongue of the plate member being depressed until the end ofthe stay rod is positioned upon the horizontal extension 12 of the hookmember 13 a sutlicient distance, after which the end of the springtongue 17 will serve to retain the end of the stay rod 10 upon the hookmember.

lVhen it is desired to remove the stay rod from the hoolrmember, thespring tongue 17 is manually depressed, thereby permitting the stay rodto be removed from the hook member.

It will be seen that there is thus provided an arrangement for mountingthe stay rods in heddle frames which may be inexpensively constructed,and whichA permits the stay rod to be mounted and dismounted withrespect to the frame in a convenient and expeditious manner whenrequired.

Having thus described the nature and characteristic features of ourinvention, what we claim as new and desire to secure by Letters Patent,is: l

l. In a heddle frame, Vthe combination of top and bottom rails, hookmembers mounted a stay rod having its ends apertured to lengage the hookmembers, and devices having depressible spring tongues extending underthe hook members and adapted to maintain the stay rod normally thereon.

2. In a heddle frame, the combination of top and bottom rails, hookmembers mounted in the topl and bottom rails, a stay rod having its endsapertured to engage the hook members, and plate members secured to the.top and bottom rails, each of saidplate members having a depressiblespring tongue, said spring tongues extending under the hook members andadaptedto maintain the stay rod normally thereon. Y

3. In a heddle frame, the combination of top and bottom rails, heddlesupporting rods, hook members mounted in the top and bottom rails, a.stay rod having its ends apert-ured to engage the hook members, andplate members secured to the top and bottom rails, each of said platemembers having a depressible spring tongue, said spring tonguesextending under the hook members and adapted to maintain the stay rodnormally thereon, and

the stay rod having recesses in which the heddle bars are positioned andsupported.

4. In a heddle frame, the combination of top and bottom rails, heddlesupporting rods, hook members in threaded engagement with the top andbottom rails, a stay rod having its ends apertured to engage the hookmembers, and plate members secured to the top and bottom rails, each ofsaid plate members having a depressible spring tongue, said springtongues extending under the hook members and adapted to maintain thestay rod normally-thereon, and the stay rod having recesses in which theheddle bars are positioned and supported.

5. In a heddle frame, the combination of top and bottom rails, a stayrod extending therebetween, members carried by the top and bottoni railsadapted to be detachably engaged by the ends of the stay rod, anddevices having tongues normally engaging the ends of the stay rod tomaintain the same in engagement with the aforesaid members carried bythe top and bottom rails, said tongues being depressible to free theends of the stay rods.

In testimony whereof, we havehereunto signed our names.
